HEATING APPARATUS FOR FIRE-ENGINES.

H SPECIFICATION forming part of Letters Patent No. 395,093, datedDecember 25, 1888.

' Application filed June 11, 1888. gerial No. 276,669. (No model.)

To aZZ whom it may concern:

Be it known that we, HARRY TRASK, residing in the city of Brooklyn,county of Kings, and State of New York, and XVILLIAM N.

. GARMICHAEL, of the city, county, and State of New York, have inventedcertain new and useful Improvements in Heating Apparatus forFire-Engines, of which the folhiiwing is a specification, referencebeing had. to the accompanying drawings.

Our invention relates specially to the economical use and manipulationof steam as a means for heating, boiling, and raising to asteam-pressure the water contained within the boiler of a fire-engineand its connections while at rest in the engine-house preparatory to ahasty exit of suchengine at the breaking out of a fire.

It consists in the construction, arrangement, and combination of theseveral parts or portions comprising the apparatus, as hereinafterdescribed and specified.

In the accompanying drawings, Figure 1 represents a side elevation of aplant embodying our improvements. Fig. 2 represents a partial view ofthe same, and Fig. 3 represents aspecial detail of improved slip-jointconnection between the heating apparatus and the engine. In Fig. l theengine is represented in place and at rest with the boiler connected tothe heating apparatus. In Fig. 2 the engine is disconnected and removedand the circulation-pipes showndropped within the flooring out of theway and circulationconnections closed.

Similar letters of reference designate like parts or portions in all thefigures.

The letter A designates a main steam-supply pipe connecting with aneighboring boiler or with a street-supply system, such supply beingpreferably of high temperatures and pressures.

B designates a pressure-regulator, whereby the higher pressures suppliedare reduced to the required pressure for steaming, the temperature beingkept at as high a degree as possible. This regulator is located in thepipe-connection between steam-supply pipe andthe heating apparatus.

0 designates a coil or pipe system, to which the steam from the supplyis passed from the with upright pipes G andG, passing up through thefloor of the engine-house.

g and g designate a pair of three-way valves located within uprightpipes G and G, by means of which the upper portions of said pipes areemptied upon the witlnlrawal of the fire-engine.

H and H designate slip-joints connecting the uprights G and G with thehorizontal branches I and I, directly attached to the fireengine boiler.At the outer or slip-joint end of these connections I and I K and K arelocated for closing such connections immediately upon the withdrawal ofthe fire-engine to prevent the blowing out of the boiler. Extra screwstop-valves, J and J, are fitted in these pipes I and I to be ready incase the check-valves should not operate. Both the pipes I and I anduprights G and G are shown out of line with each other, the bet ter todisplay both inlet and outlet circulationconnections. In practice theywould naturally be put in line with each other.

L designates the fire-engine boiler, within which the steam-pressure isrequired to be raised and kept up by the apparatus while the engine ishoused.

M designates the main floor or apartment, containing the engine while atrest.

M designates the basement, cellar, orlower floor of the engine-house,containing the heating apparatus.

N N are positive connections attached to timber between enginefioor andbasement, adapted to operate the levers of the two three- Way valves 9and g to open or close the three- Way passages for the purpose offorming a continued connection through uprights G and G or of closingsaid connection and effecting the emptying of the water left in uprightsG check-valves and G after the withdrawal of the engine. These valves gand g discharge to a sewer or drain through pipes g A specialoperating-rod, O, is attached to levers P, connected to and operatin gvalves E and E, and adapted to project up through the flooring-betweenmain and basement portions and to be raised and lowered from above theflooring, cfi ecting the opening and closing of the valves. A specialshore, Q, is set to sup port this red O in a lifted position. The shoreQ is held in its upright supporting position by a hook, R, attached tothe fire-engine plat- :form.

The detailed construction of the slip-joint H betuveen engine-pipes Iand uprights G is shown in special, Fig. 3. The lever T,to which isattached the stem of the check-valve K, is fastened and swings at t onpipe I, and is fitted with 'a hook, '1 and lifting eye or pin Theslip-joint II is fitted with a slotted boss, Z provided with awedgeincline, t also the male and female portions 7L2 and 7t". In makingthe connection of this slip-joint the fireengine is moved backward,presenting the portion b to enter the sleeve h. The entrance of 71 intoit enters the lever T into slot 25 and the final connection is made bythe hooking of t without the slot i The movement of the lever into theslot carries the end of lever T up the wedge-incline i, lifting the stemof valve K and opening it ready :for work. As the hook portion 25 exitsfrom the slot i it drops into place to hold the slip-joint together.

In. the general operation of this apparatus as a whole the live steamenters through or from suppl y-pipe A, and is passed through thereducing-valve B, reducing the steam-pressure from its maximum in thesupply-pipe to a pressure best suit-able to the furnishing of heatsuflicientto develop a pressure of some fifteen, twenty, or twenty-fivepounds within the fire-engine boiler. \Yith a high quality and pressureof steam from the supply the pressure beyond the reducing-valve may beregulated to a pressure of fifteen to twenty pounds, and with ampleheating-s11 rface a pressure of twenty to twenty-five pounds can beeasily kept up in the fire-engine boiler. As the water in tank orchamber D becomes heated, it rises and passes through upper Valve, E,hinge-connection F, upright G, slipjoint H, check-valve K, and pipe I tothe fireengine boiler, thence down again through pipe I, check-valve K,slip-joint I-I, upright G, hinge-connection F, and lower pipe and valve,E, back to the heater tank or chamber D.

Upon an alarm of fire lever T is raised and unhooked at t and the engineis released.

Upon moving out, the shore Q is pulled from under the red O by hook R,when the whole falls within the pocket S below the level of flooring.The dropping of rod 0 closes both valves E and E by the movement oflever P on each after ordinary methods, the weight 0 assisting in thedownward movement of rod 0. The separating of the slip-joint IIwithdraws all support from pipes G and G, and they too settle down intothe pocket S beneath the floor-level, and the check-valve K, rod R, andlever T move away with the fire-engine. Thus is the fioor left clear forthe passage of anything else. The dropping of the pipes G and G to theposition below the floor-level, as shown in Fig. 2, causes the openingof the valves g and g to the drainpipe g through the pull brought tobear upon their levers by the connections N and N, hung from thefloor-beams above.

Upon the return of the engine it is backed toward the slip-joints, pipesG and G are lifted to the proper level to receive plug 7L2, theconnections made, and lever T moved to a hooking at I. The lifting ofthe pipes G and G effects the closing of the drain-outlet of valves gand g and the opening of direct communication from the lower to theupper portion of uprights G and G. \Vith the closing of the slip-jointII red O is lifted, opening valves E and E and effecting the completeconnection of the apparatus. IVith the lifting up of the rod 0 shore Qis set to hold it up, and hook-rod R is adjusted to keep the shore Q. inplace till the engine upon moving away pulls it from under.

The hinge portions are fitted to revolve at both ends and permit thelowering of uprights G and'G, as shown in Fig. 2, such hinge portionsbeing seen to point downward in this figure, instead of upward, as inFig. 1. If only low-pressure steam can be had, there is of course nonecessity for the reduci n g-valve.

\V hat we claim as new, and desire to secure by Letters Patent, is

8. In a heating apparatus for fire-engines, in combination with awater-heating chanr portion of inlet and outlet connections, a pair ofoperating-levers attached to said drain-valves, and suspension-rodsattached to said levers whereby, the fire-engine moving away, theconnections are released and drop to a pocket in the floor andcommunication with the heater is closed, substantially as set forth.
